My GPIRB (IPRO 406 MHz GPS) is registered to me and my boat
. I will, however, be crossing the Pacific with a friend on his boat
while my boat remains in on the hard
. I am considering taking my GPIRB in my ditch bag as an alternate / backup to his EPIRB
and his ditch bag. Is it important to temporarily change the registration
to link my GPIRB to his boat? Where might I find the procedure to do so?
